Package Web Development

Symfony is a PHP framework and set of component libraries designed to help developers build web applications, APIs, and web services.

Symfony follows the MVC (Model-View-Controller) Architecture that makes code more organized, maintainable, and testable.

Symfony comes with a built-in libraries to handle common tasks, saving development time. Symfony integrates with template engines like the Twig template or other options such as Smarty to further separate the presentation layer from code. Symfony can be extended by third-party libraries, helpers, and plugins to customize its functionality to fit your project’s specific needs

Requirements For Symfony

Glossary

Model

Represents the data and business logic. Interacts with the database (CRUD operations), performs calculations, and handles data processing.

View

Responsible for displaying the user interface. Contains HTML, CSS, and potentially some PHP for data presentation.

Controller

Acts as the intermediary. Receives user requests, loads models, interacts with them to retrieve data, and then loads the appropriate views to display the results.

Download

Symfony can be downloaded from Symfony. Then the downloaded file is executed directly on the server or locally before installation based on the operating system.

Web Portal

The Symfony development server interface can be accessed at the following URL https://localhost:8080.
